While you can't Normal or Special Summon a monster with the same name if you have a Spell/Trap Card in your Graveyard, you can still add a Machine-Type Pendulum Monster that ended up in your Graveyard and activate it during the same turn, such as "Symphonic Warrior Guitaar" or "Dinomist Brachion".

Special Summon "Speedroid Terrortop" from your hand, then use its effect to add "Speedroid Red-Eyed Dice" from your Deck to your hand, and Normal Summon it to Synchro Summon this monster, and return any "Speedroid" monster in your Graveyard back to your hand.

Special Summon "Speedroid Terrortop" from your hand, then use its effect to add "Speedroid Taketomborg" from your Deck to your hand, then Special Summon it by its own effect. Further Special Summon "Superheavy Samurai Trumpeter", Synchro Summon this card, then (if your have no Spell/Trap Cards in your Graveyard) add Trumpeter back to your hand. From there, you can Special Summon it to Synchro Summon another copy of this card and return Terrortop to your hand for next turn.

"Superheavy Samurai Gigagloves" is a good Level 3 Monster to use as Synchro Material along with "Superheavy Samurai Trumpeter", as it's effect will activate letting you stack the top 5 cards of your deck, you can return Trumpeter to your hand with this card's effect, then Gigagloves will stay in the Graveyard so you can use it's other effect.
